Re-Thinking criminal Defense
When it comes to your freedom and reputation: 100% Criminal Defense Lawyer.
With us there is no room for “criminal law on the side”: the criminal defense lawyers of our, in Germany, in the Aachen area located, lawyer boutique focus on criminal defense for private individuals. We are not “lawyers for everything”, but have recognized early on that in criminal law you need absolute professionals who do not get bogged down – so that clear announcements also have a real value. Because criminal charges are not only about the punishment, the sanction alone, but also always about your reputation. In social and business life, your reputation, your good name, is of particular importance – we find face-saving solutions so that your life can go on.
Criminal defense has been rethought by us: the model we have developed, “Consult different“, is based on an extremely factual approach as well as the American model, which is characterized by a much more personal approach by lawyers. Because if you feel lonely and lost in a criminal case, you need a direct contact with time, honesty and empathy.
Language barriers: we close the gap! German criminal procedure is complex even for native speakers. For international clients, it can be almost impenetrable. We therefore routinely organize professional interpreters for meetings and court hearings, arrange translations of key documents from the case file – even where there is no strict legal entitlement – and provide detailed explanations of every step in English. You will always know what the authorities are doing, what your options are and why we recommend a specific course of action.
On the run – German arrest warrant or European Arrest Warrant?
We regularly defend clients who are already abroad, have gone into hiding or are confronted with a German arrest warrant or a European Arrest Warrant. In these situations, early and discreet legal advice is crucial: every move – travelling, contacting family, logging into accounts – can have legal consequences. We help you understand the real risks, the options for surrender or negotiated return, and the impact on extradition proceedings.
Support for family members
Very often, family members are the first to contact us. We explain the situation in clear terms, coordinate contact with the person on the run where possible, and take over communication with the German authorities and courts. If required, we also organize interpreters, so that everyone involved truly understands what is happening and why a specific strategy is chosen.
Secure communication – even if you are on the run
Many of our clients contact us while they are already abroad, under investigation or facing an arrest warrant in Germany. We know that discretion and digital security are crucial. That is why we rely on European infrastructure and end‑to‑end encrypted tools only: Threema for messaging (ID: FVNW2K7T), Proton‑based email and our own fully‑encrypted Nextcloud instance for file exchange. If you are worried about surveillance, do not call from insecure lines – start with an email or a Threema message.
Please contact us first by email (kontakt@ferner‑alsdorf.de) or Threema. We will then decide together whether and when a phone or video call makes sense in your situation.
